Abstract An array of novel chiral aromatic heterocyclic macrocycles, which may show potential enantiomeric recognition to variable D- and L-amino acids, were synthesized in acceptable yield. The desired macrocycles 3a–c and 4a–c were obtained via the condensation reaction of chiral diamine intermediates 2a–c with 2,5-bis(o-chloroformylphenyl)-1,3,4-triazole 5 in a presence of Et3N in a highly diluted
摘要 以可接受的收率合成了一系列新型手性芳香杂环大环,它们可能对可变的 D- 和 L- 氨基酸显示出潜在的对映体识别能力。所需的大环化合物 3a-c 和 4a-c 是通过手性二胺中间体 2a-c 与 2,5-双(邻氯甲酰基苯基)-1,3,4-三唑 5 在 Et3N 存在下的缩合反应获得的室温下高度稀释的二氯甲烷溶液。
